[0001] The invention belongs to the technical field of cable coating processing, in particular to a wire and cable coating device. Background Art

[0002] Wire and cable covering, also known as wire encapsulation technology or extrusion, is a crucial process in the production of wires and cables. It mainly uses specific materials and equipment to wrap one or more protective layers on the outside of the conductor of the wire and cable to achieve the purpose of protecting the wire and cable, improving insulation performance, and extending service life.

[0003] The existing wire and cable covering devices still have drawbacks in actual use: during use, the conductors used in cable manufacturing are easily contaminated by the external environment during transportation, resulting in impurities on the outer wall of the conductor. In order to save costs, some factories used for manufacturing wire and cable coverings have a relatively poor factory environment and fail to ensure the cleanliness of the conductor surface in the early stage of covering. When the conductor is not in a clean state, it is easy for the rubber sheath used for covering to not fit tightly to the outer wall of the conductor when it is covered by the covering machine, thereby affecting the subsequent covering effect.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention arranges the coordination of structures such as a card shell and a driving module, thereby preventing the surface of the conductor of the cable body from being attached with impurities due to the influence of the transportation environment and other factors when the cable body is directly used for coating, thereby reducing the subsequent coating effect. The belt transmission module can respectively make the upper and lower card shells move back and forth on the surface of the cable body through the spur gears and the protrusions. Through the reciprocating rubbing of the card shells, the impurities that are tightly attached to the surface of the conductor of the cable body are scraped and cleaned, thereby ensuring preliminary cleaning.

[0026] The present invention utilizes the wetting of water source by setting up the cooperation of structures such as the resisting rod and the resisting block, thereby improving the cleaning effect on the outer wall of the cable body; when the non-protruding end of the protrusion does not resist the movement of the resisting rod, the resisting rod will be reset by the elastic force of the first spring, and the first spring will resist the resisting block, so that the resisting block squeezes the sponge, and the sponge is squeezed to cause the internal water to penetrate into the interior of the first wiping cotton through the rectangular groove inside the card shell; the soaked first wiping cotton moves with the card shell to comprehensively clean the surface of the conductor of the cable body, thereby greatly improving the cleaning effect.

[0027] The present invention ensures the cleanliness of the surface of the conductor of the cable body before the cable body is coated by arranging the cooperation of structures such as the threaded ring and the second wiping cotton. During the movement of the push rod, due to the threaded sleeve connection between the threaded ring and the inner wall of the positioning module, the threaded ring is pulled by the limiting ring to drive the second wiping cotton to rotate and wipe the outer wall of the cable body. The second wiping cotton will rotate and wipe the water stains on the surface of the cable body caused by wiping with water, thereby ensuring the cleanliness of the outer wall of the conductor of the cable body when entering the coating machine.

[0028] The present invention improves the tightness between the rubber sheath and the cable body conductor after coating by arranging the cooperation of structures such as a limit shell and an abutting rubber plate. When the threaded ring moves in the inner cavity of the positioning module, it will synchronously drive the connecting frame to move. At this time, the end of the connecting frame away from the positioning module will drive the limit shell and the abutting rubber plate to squeeze the cable body coated with the rubber sheath, so as to improve the tightness between the rubber sheath and the cable body.

[0046] The cleaning module 6 includes a clamping assembly 61 disposed on the upper and lower sides of the outer wall of the cable body 5, the clamping assembly 61 includes a card shell 611, the inside of the card shell 611 is movably connected with a stopper 612, the bottom of the stopper 612 is abutted with a sponge 613 placed inside the card shell 611, and the bottom of the card shell 611 is bonded with a first wiping cotton 614;

[0047] The driving module 7 includes a spur gear 73, and the outer wall of the spur gear 73 is meshedly connected with the upper and lower clamping shells 611;

[0048] The resistance module 8 includes a fixed block 82 installed in the inner cavity of the positioning module 1, and a resistance rod 81 is slidably connected to the fixed block 82. The end of the resistance rod 81 away from the fixed block 82 abuts against the resistance block 612. The end of the resistance rod 81 away from the resistance block 612 is fixedly connected to a limiting ring 84. The end of the limiting ring 84 away from the resistance rod 81 is movably clamped with a threaded ring 85. The inner cavity of the threaded ring 85 is installed with a second wiping cotton 86 wrapped around the outer wall of the cable body 5.

[0049] like Figure 1 As shown, the positioning module 1 includes an upper shell 11 and a lower shell 12 connected by bolts. A cross bar is arranged at one end of the upper shell 11 and the lower shell 12 close to the coating machine 4. The upper shell 11 and the lower shell 12 are bolted to the coating machine 4 through the cross bar.

[0050] The above solution is adopted: the upper shell 11 and the lower shell 12 are placed on the outer wall of the cable body 5 by bolts, and the upper shell 11 and the lower shell 12 are connected to the coating machine 4 by a cross bar, so as to achieve the stability of the upper shell 11 and the lower shell 12.

The end of the connecting frame 2 away from the circular groove is bolted to a fitting module 3 coated on the outer wall of the cable body 5, and the middle end of the connecting frame 2 is movably engaged with the coating machine 4.

[0052] By adopting the above solution, when the threaded ring 85 moves, the circular ring groove opened in the inner cavity of the threaded ring 85 will enable the connecting frame 2 to drive the bonding module 3 to move synchronously on the outer wall of the cable body 5. The connection between the connecting frame 2 and the coating machine 4 ensures the stability of the connecting frame 2 during the movement.

[0053] like Figure 5 and Fig. 9 As shown, the fitting module 3 includes a limiting shell 31 connected to the connecting frame 2 with bolts, and the upper and lower sides of the limiting shell 31 are movably connected to the limiting posts 33, and the adjacent ends of the two limiting posts 33 are fixedly connected to the abutting rubber plates 32 located on the outer wall of the cable body 5, and the outer wall of the limiting post 33 is sleeved with a spring, and the abutting rubber plate 32 is elastically connected to the limiting shell 31 through the spring;

[0054] Both ends of the two abutting rubber plates 32 are provided with bevels.

[0055] The above scheme is adopted: the opening of the oblique angles at both ends of the abutting rubber plate 32 allows the cable body 5 to move smoothly to the middle area between the upper and lower abutting rubber plates 32, and through the spring sleeved on the outer wall of the limiting column 33, the abutting rubber plate 32 squeezes the sheath after the sheath is sleeved on the outer wall of the cable, thereby improving the close fit between the sheath and the cable surface.

[0056] like Figure 4 , Fig.10 and Fig.11 As shown, a screw rod 62 is slidably connected to one side wall of the two housings 611 opposite to each other, and one end of the screw rod 62 away from the housing 611 passes through the positioning module 1 and is threadedly connected to the inner wall of the positioning module 1. A water pipe 63 is installed on one side of the upper and lower housings 611, and the contact end of the water pipe 63 and the housing 611 is used to replenish moisture to the sponge 613.

[0057] like Fig.10 and Fig.11 As shown, the contact end of the stop block 612 and the connecting frame 2 is provided with an oblique angle, the stop block 612 extends from the middle end of the side wall of the sponge 613 to the inside of the card shell 611, and the stop block 612 extends to the outer wall of the end of the card shell 611 and is provided with a spring to reset the stop block 612.

[0058] Tension springs are provided on both sides of the card shell 611, and the card shell 611 is elastically connected to the inner cavity of the positioning module 1 through the tension springs.

[0059] like Fig.10 As shown, the contact end of the card shell 611 and the cable body 5 is semicircular, and the contact end of the card shell 611 and the first wiping cotton 614 is provided with a plurality of rectangular grooves;

[0060] When the sponge 613 is compressed by an external force, the water inside the sponge 613 will penetrate into the first wiping cotton 614 through the rectangular groove.

[0061] like Figure 6 and Figure 7 As shown, the driving module 7 includes a belt transmission module 71, which is composed of a motor, a rotating shaft and a belt. The middle rotating shaft is fixedly connected to a spur gear 73, and bumps 72 are fixedly connected to the rotating shafts on both sides.

[0062] like Figure 7 As shown, the end of the protrusion 72 abuts against the abutting rod 81, and the outer wall of the spur gear 73 is only provided with two sets of mutually symmetrical tooth rings, which are respectively meshed and connected with the upper and lower clamping shells 611.

[0063] With the above solution, when the belt drive module 71 rotates, the spur gear 73 in the middle will drive the upper and lower casings 611 to move in opposite directions, and the protrusion 72 will also push the lever 81 to move as it rotates. Figure 7It can be seen that when the spur gear 73 is continuously rotating, the side wall of the outer wall of the spur gear 73 without teeth will not drive the jammer 611 to move. At this time, the jammer 611 will be reset by the elastic force of the tension spring, but at the same time, the rotation of the protrusion 72 is continuous. When the non-protruding end of the protrusion 72 does not resist the movement of the push rod 81, the push rod 81 will be reset by the elastic force of the first spring 83, and the first spring 83 will resist the push block 612, so that the push block 612 squeezes the sponge 613.

[0064] like Figure 8 As shown, the push rod 81 is elastically connected to the fixed block 82 through the first spring 83, the second wiping cotton 86 is composed of two arc-shaped sponges with magnetic blocks, the upper shell 11 and the lower shell 12 are spliced ​​to form a circle, and the threaded ring 85 is threadedly sleeved with the inner cavity of the positioning module 1.

[0065] The working principle and use process of the present invention:

[0066] First, the positioning module 1, the connecting frame 2 and the bonding module 3 are installed on the outer wall of the cable body 5 and connected to the coating machine 4. When the wire first enters the first wiping cotton 614, the belt transmission module 71 is started. The belt transmission module 71 will drive the upper and lower card shells 611 to move in opposite directions through the spur gear 73 and the protrusion 72, and the more protruding end of the protrusion 72 will contact the rod 81 to displace. The upper and lower card shells 611 will reciprocate on the surface of the cable body 5 to preliminarily clean the outer wall of the conductor of the cable body 5. The spur gear 73 is kept When the rotation continues, the side wall of the outer wall of the spur gear 73 without teeth will not drive the jamming shell 611 to move. At this time, the jamming shell 611 will be reset by the elastic force of the tension spring, but at the same time, the rotation of the protrusion 72 is continued. When the non-protruding end of the protrusion 72 does not resist the movement of the push rod 81, the push rod 81 will be reset by the elastic force of the first spring 83. The first spring 83 will resist the block 612, so that the block 612 squeezes the sponge 613. The sponge 613 is squeezed, causing the internal water to penetrate into the first wiping cotton 614 through the rectangular groove inside the jamming shell 611.

[0067] As the jamming shell 611 drives the soaked first wiping cotton 614 to move, the first wiping cotton 614 cleans the impurities on the outer wall of the conductor of the cable body 5 more comprehensively. During the movement of the stop rod 81, the stop ring 84, the second wiping cotton 86 and the threaded ring 85 will move simultaneously. Due to the threaded sleeve connection between the threaded ring 85 and the inner wall of the positioning module 1, the threaded ring 85 will drive the second wiping cotton 86 to rotate and wipe the outer wall of the cable body 5 when being pulled by the stop ring 84. The second wiping cotton 86 will rotate and wipe the water stains on the surface of the cable body 5 caused by wiping with water, thereby ensuring the cleanliness of the outer wall of the conductor of the cable body 5 when entering the coating machine 4.

[0068] Finally, when the threaded ring 85 moves in the inner cavity of the positioning module 1, it will synchronously drive the connecting frame 2 to move. At this time, the end of the connecting frame 2 away from the positioning module 1 will drive the limiting shell 31 and the abutting rubber plate 32 to squeeze the cable body 5 covered with the rubber sheath, so as to improve the tightness between the rubber sheath and the cable body 5.
